Disklavier

I have been trying for the last several days, and many hours to figure 
out how to hook up to these services to my Mark IV, but have not been 
successful.  I looked at the V2.0 users manual, and it says to sign up 
for IDC online, which I did succesfully (can log on to the Yamaha 
website, and it says that I am registered and able to access IDC).  It 
also says that you sign in to these services via the handheld remote, 
but I cannot find any screen or menu on the remote to do this.  

I have hooked the piano to a hard-wired ethernet connection to the 
internet.  What am I not doing?
